4 Claims. .(Cl. 277-32) ingly fbe necessary to repeatedly regulate each valve. VVRather than tofgo through this-troublefsomefproceduraa person-isroften inclined to allow `the Lwater tof-run continuouslylforilong periods of time, once aproperregulation haslbeen. effecftuated-a rprocedurefwhich obviously :results in a 4considerable waste of water., yaswell .as of fuel fnecessary-to heatthe'water.

It yis primarilywithinfthe. contemplation of 'my invention tozfa'cilitate the regulation of .hot and -cold water valvesywhereby ithe: .aforesaid shortfcomings. of, conventional structures will .be:elim- .inated, ,And viin this aspect ,offmy invention, .it is an object to provide'a valveprovided'with:means for regulating the owof water therethrough whereby, once a desired'settingrisfestablished,:the `proper-flow can be obtained'by 'merely turning amain `valve'to a singleopenaposition. In this manner, all that'needfbadone after the valve-is once set, is merely-toppen it as `iar as it will go, -whereupon vthe proper iiowH ofwater wi11.course therethrough. It i-s thus apparent that byproviding' adja-cent hot and cold water faucets with valve structures of my invention, a conventional mixer-.can be attachedthereto .to combine predeterrnnedilows from .both faucets and thereby produce a-.Dredetermined temperature.

It is within .the further vcontemplation 0f my inventionto provide a-.device of the above-mentioned, category .in `a single unitary structure, .thereby producing asimpla'inexpensiveand comlpact unit. A

AOther -.objects,.features andv advantages will appear from -the --drawing and `the description :hereinaftergivem Referring vto the drawing; Figure 1 is a vertical sectional view .taken substantially, along .the axis of a formof vvalve lof lmy invention. i

Figure 4 is va fragmentary section takensubstantially along line 4 4 of Figure l.

The drawing shows my `invention as applied to a 4faucet although it may just as conveniently and electively be employed in any other valve fitting. The casing 5 of the faucet illustrated contains an inlet 6 and an outlet or discharge'conduit 1,

both communicating with vthe main valve chamber 8. Rotatably disposed within` said lchamber -is the main valve member 9 containing a trans- -verse passage I adapted for yregistry and-cooperative use with said inlet and outlet conduits 6 `and 7. Said main valve 9 is provided at'the lower `portion thereof with a pin or extension II movable within the recessed portion I2, preferably .at the lower portion ofthe casing 5said 4recessed portion containing walls I3 and I 4 serving as stops abuttable with the extension II for the purpose of limiting the operative movement of main valve 9. When the extension is inengagement with wall I3, theV passageway I!) is in communication withconduits 6- and l to permit the passage of water therethrough; and when the saidextension is in engagement with Wall i4, said passageway is entirely out of communication with said conduits, the lateral wall I5 of the valve being disposed against the adjacent openings of *conduitsV S and "i, respectively, to prevent the passage of Water therethrough. It is preferred that walls I3 and Ill be `90 apart, so that the main valve 9 can be rotatably manipulatedthrough an Yangle of to full open and closed positions.

The upper portion I6 ofthe main valve constitutes the valve stem thereof, being in the form of a sleeve extending upwardly through the gland Il secured to the body 5 of the faucet and holding the packingl I8 in operative `position to pre- -vent leakage. Said upper portion IB of the valve stem is joined to the handle I9 for manually manipulating the valve. In the form of construction illustrated, the valve stem has a threaded recess therein in threaded engagement with the stud 20 of the saidhandle.

Extending through the hollow stem I5V is an auxiliary stem 2| carrying, by means of the thread 22, an auxiliary valve 23 axially movable within main valve 9 and adapted to intercept the passageway Ill-therein. The said auxiliary valve contains longitudinal ribs or extensions 24 slidaloly .movable Within grooved guides 25 within the main valve--the auxiliary valve further con- Ttaining an enlarged portion 26 adapted yfor =en sagement with the auxiliaryvalveseat S21 4-onfthe main valve 9. The auxiliary valve also contains the threaded axial recess 28 in operative engagement with the threaded portion 22 of the auxiliary stem 2 l. The arrangement is such that upon a rotation of the auxiliary stem, the auxiliary valve 23 will be caused to move up or down Within the main valve 9.

Attached to the upper portion of the auxiliary stem is the manually operable knob 29 containing a pointer 30 thereon, the underside of said knob being disposed over the upper flat surface 3l of the main valve stem I6. Upon said surface 3l are a series of markings 32 coactively associated with said pointer 30.

It is preferred that the knob 29 rest upon the surface 3| which will thereby serve as a support for the entire auxiliary valve assembly. The main valve, in the preferred form illustrated, is made of two sections, the lower section 9a. being in eiect a packing gland supporting a packing 33 against the auxiliary valve 23 to prevent a leakage of water therepast to the space 34 above the Valve seat 2l. The two sections of the main valve can be secured together in any suitable manner, such as by the threaded means 35.

In the operation of the form of my invention above-described, the main valve handle i9 is manipulated to turn the main valve 9 into its open position so that the passageway lil is in direct communication between conduits 6 and 1, thereby permitting water to ilow therethrough. Thereafter the regulating knob 29 is rotatably manipulated to cause a lowering of the auxiliary valve 23 within the passageway i0, this lowering being eifectuated by the cooperation of the threaded stem 22 and recess 28, particularly inasmuch as the auxiliary valve is held against rotation by the ribs 24 slidably movable within the guide recesses 25.

The position of the auxiliary valve 23 will, of course, determine the amount of water flowing through the outlet 1. Hence, when two such compound valve structures are employed in adjacent relationship, one for hot and one for cold water, and both outlet pipes, such as the conduit 1, are connected by a mixer, it is apparent that a control of the temperature of the water ilowing through the mixer can thus be eiiectuated, the position of the auxiliary valves in the hot and cold water valves determining the flow of hot and cold water, respectively.

Once the knobs 29 on the hot and cold water faucets are set for a particular temperature in the mixer, no further regulations or settings need be effected. All that is required is that the main valve handles l 9 be turned on to their open position, and water of required temperature will enter the mixer. Should intermittent use of water be required, such as in the case of shaving, the main valve handles I9 are merely turned off when the water is not required and then turned on when it is required, and the desired temperature will in each case be attained.

Repeated resettings for predetermined temperatures can readily be eiected by noting the position of each pointer 30 with respect to the. markings 32 on surface 3|, and settingthe knobs 29 accordingly.

It is of course understood `that the embodiment above-described and shown in the drawing is illustrative of my invention and is not employed by way of limitation, inasmuch as numerous changes andi modifications may be .made

therein within the scope of the appended claims vprojected position.

without departing from the spirit of this invention.

What I claim is:
